Description of intervention(s) / exposure
High frequency chest wall oscillation (HFCWO) is an airway clearance technique recommended for respiratory management of neuromuscular conditions. This technique applies oscillations to the chest via a vest or wrap using an air pulse generator at a frequency of up to 20 compressions per second. These oscillations are thought to generate shearing forces and bias expiratory flow in the airways, facilitating secretion clearance. Participants will receive HFCWO regardless of their involvement in this study. Observational measurements will be taken for the duration of each physiotherapy intervention and repeated daily until discharge from PICU.
Intervention code [1] 317212 0
Not applicable
Comparator / control treatment
Standard physiotherapy treatment consisting of a combination of positioning, percussion, expiratory vibration, manually assisted cough, mechanically assisted cough and airway suctioning. These modalities may be used individually or together with the aim of optimising airway clearance. Participants will receive standard physiotherapy treatment regardless of their involvement in this study. Observational measurements will be taken for the duration of each physiotherapy intervention and repeated daily until discharge from PICU.

Summary
Brief summary
Patients with neuromuscular disease can have impaired airway clearance which may lead to respiratory deterioration and death. Physiotherapy is vital in assisting with airway clearance for this patient population. Recent studies have suggested the use of high-frequency chest wall oscillation (HFCWO), however, there is little physiological evidence to support its efficacy. This study will use electrical impedance tomography and lung ultrasound to assess pre and post-treatment lung volume changes for patients receiving standard chest physiotherapy and HFCWO.
